Marriage definitely means different things to different people...I watched my own parents drift slowly apart until there was no longer a core of "we" in my family, and they divorced when I was 15 years old.
I work HARD every single day at making my marriage a living and breathing thing...if someone tells you they don't argue and things are lovely, then when the really horrible things happen, how do they suddenly do hard and crappy? I have seen my Kasey at her rock bottom worst, and she has seen the same in me...but the little things like waiting out in the parking lot at the grocery store so she can load the groceries, or my putting a blanket around her shoulders when she is too busy at work to get one herself...those intimate things we do because we love and support one and other, (for us) those things can't be done from 2 separate houses across town from each other.
When she shows me some stupid FB picture of a hedgehog in a tux while we sit and watch a game show, just to see me smile...I know I wouldn't want to miss any part of her life for a few moments of alone time.
But then, I'm a sap
